Coljam
Coljam
Also known as: Colombian Gold x Jamaican Lambsbread, Col'Jam
Overview
Coljam is a pure sativa cannabis strain created by Underground Seeds Collective as an F1 cross between Colombian Gold and Jamaican Lambsbread. This strain represents a genetic fusion of two legendary landrace varieties that shaped the cannabis industry - Colombian Gold, which served as parent genetics for renowned strains like Skunk #1, and Jamaican Lambsbread, famously associated with Bob Marley. The breeding combines the high-altitude adaptation and mind-blowing potency of Colombian Gold from the Sierra Nevada de Santa Marta mountains with the pure sativa landrace characteristics of Jamaican Lambsbread that adapted to the Jamaican climate after arriving from Africa.
Coljam exhibits typical sativa characteristics with tall plants that stretch significantly and bloom in 14-16 weeks. The strain presents a complex terpene profile featuring spicy, hazy, resin, and slightly fruity aromas according to phenotypes, with updated descriptions noting fruity flavors of peach and orange with spicy notes and hazy characteristics. The newer version shows impressive vigor with flowering times around 18 weeks and very good production that compensates for the long flowering period, yielding up to 600 grams per square meter.

Growing Information
Indoor cultivation requires a flowering time of approximately 105 days (14-15 weeks), though newer versions may take up to 18 weeks. Plants grow very tall and stretch significantly, requiring adequate vertical space and training techniques. Plants exhibit impressive vigor during growth. Expected yields can reach up to 600 grams per square meter indoors. Growing difficulty is considered moderate to advanced due to the long flowering period and height management requirements. Only regular seeds are available, never feminized. The strain requires experienced cultivation techniques to manage the extended flowering time and substantial plant size.
